Abstract
The invention discloses a polishing unit for steel rail polishing vehicles. The polishing unit comprises a swing basket and is provided with tilting devices. A plurality of polishing heads are fixed into the swing basket, and each polishing head comprises a polishing grinding wheel and a polishing motor and is provided with a clamping device and a lifting device. A fire damper board is mounted on the outer side of the polishing unit, and a protective cover is mounted below the polishing motor of each polishing head. A rail outline polishing vehicle comprises four polishing units, and each polishing unit comprises two polishing heads; a corrugation polishing vehicle comprises two polishing units, and each polishing unit comprises four polishing heads. The polishing unit has the advantages that the polishing unit is applicable to the various steel rail polishing vehicles, is used for amending wavy abrasion of rails and scratching of wheel rails, correcting tilting deformation of inner and outer rails, trimming contact surfaces of the wheel rails and the like, accordingly, the various defects of the steel rails caused when vehicles run on the steel rails can be overcome, and the steel rails of lines can be preventively maintained; the polishing unit is excellent in cost performance and low in maintenance cost.
Description
Technical field
The present invention relates to a kind of rail prosthetic device, relate in particular to a kind of rail grinding machine polishing unit.
Background technology
The 1950's, along with the fast development of various countries' economy, railway transportation freight volume and the speed of service are comparatively fast developed.Thereupon, rail waveform wears away, contact fatigue equivalent damage is more and more serious, affects safety and the economy of railway transportation.It is more and more important that the maintenance of rail just seems, occurred rail grinding machine, and rail is carried out to sanding and polishing.
In prior art, divide two kinds of rails exterior features and ripple mill polishing dolly according to rail profile abrasion polishing dolly, can in job run, carry out preventative and reparation property grinding to the rail on circuit, the diseases such as the abrasion of rail undaform, rail lip, saddle shaped abrasion, welding depression and fish scale crackle are polished, thereby improve the profile of rail head working portion.Extend rail application life, improve wheel rail relation, reduce noise, improve safety and reduce maintenance cost.
At least there is following shortcoming in rail grinding machine of the prior art:
Polishing block construction complexity, cost are high.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, rail grinding machine that cost is low polishing unit.
The object of the invention is to be achieved through the following technical solutions:
Rail grinding machine polishing of the present invention unit, comprises cradle frame, in described cradle frame, is fixed with multiple grinding heads, and described grinding head comprises grinding wheel and polishing motor, and each grinding head is respectively equipped with clamping device, lifting gear, and polishing unit is provided with tilting gearing.
As seen from the above technical solution provided by the invention, the rail grinding machine polishing unit that the embodiment of the present invention provides, owing to comprising cradle frame, in cradle frame, be fixed with multiple grinding heads, state grinding head and comprise grinding wheel and polishing motor, each grinding head is respectively equipped with clamping device, lifting gear, polishing unit is provided with tilting gearing, be suitable for various rail grinding machines, be used for revising the wavy wearing and tearing of track, wheel track scratch, in correcting, outer rail inclination and distortion and finishing running surface of wheeltrack etc. are various due to the vehicle steel rail defect producing that travels on rail, carry out the preventive maintenance of circuit rail.Simple in structure, cost performance is high, maintenance cost is low.
